Features and Advantages
Real online internal resistance measurement
The internal resistance test of ZCO-420 series battery monitoring and management system is completed automatically. There is no need to change the operating state of the battery pack. At the same time, in the process of internal resistance test, there is no need to discharge, which is a really safe internal resistance measurement method.
Modular structure design to meet various battery configurations
ZCO-420 series battery monitoring and management system adopts modular structure design. Each ZCO420-S module can connect up to 128 batteries in series. It can satisfy various battery system configurations through different module combinations.
System composition
ZCO420-S: battery monitoring and acquisition host, RS485 communication interface, supporting MODBUS communication protocol;
ZCM-CP-E: Ethernet module, which converts data into Ethernet communication protocol and transmits through Ethernet;
ZCM-CP-F: optical fiber module, which converts data into optical fiber protocol. And through optical fiber transmission;
ZCM-CP-G: GPRS module, which transmits data in the way of SMS, and sends the alarm information to the designated mobile phone at the first time.
